This interactive visualization maps the global availability of assistive technology education programs by WHO region, with each country color-coded by region and filterable by training content type. It uses d3.geoPath with TopoJSON world atlas data to render the choropleth map and d3.scaleBand for the stacked bar chart comparing regional program counts across cognition, communication, hearing, mobility, self-care, and vision training. Hovering reveals country-level details, while the dropdown filter dynamically updates both map and chart. Data comes from a CSV of country-level survey responses.
